Abstract In this paper, we describe the concept of setting the base of large-sized parts with a diameter of up to 8300 mm and a mass of up to 120 tons, such as a bandage of a rotating cement kiln during machining using a mobile robotic machine. The issue of controlled cutting to ensure accurate shaping of a large-sized part with a thickness of the removed metal layer up to 6 mm …

PROCESS DIAGNOSTIC STUDIES FOR CEMENT MILL …

HOLTEC has undertaken Performance Optimisation of the cement grinding circuits by doing process diagnostic studies in many cement plants. The paper describes the approach for the process diagnostic study for the optimisation of a ball mill circuit and is supported with typical case study done by HOLTEC in a 1.5 mio t/a cement plant.
